Development of Chamfer-Type Super Low Loss MPO Connector Using PPS Ferrule

摘要

In order to meet the requirements for multi-fiber and high density optical connection in DWDM (Dense Wavelength Division Multiplexing) systems, we have developed a super low loss MPO connector using injection molded PPS ferrule. Furthermore, we also propose to chamfer around the guide-pin holes near the connection end face to improve durability against repeated mating. We have confirmed that this is highly effective in preventing cracks and damage around the guide-pin holes near the end face and contribute to the stability of insertion loss levels. The trial chamfer-type single-mode MPO connectors have exhibited satisfying characteristics including maximum insertion loss of less than 0.35dB; maximum loss change of less than 0.2dB when repeatedly mated up to 500 times; and maximum loss increase of less than 0.2dB during reliability tests based on GR1435.
